What is the link between beef and Amazon deforestation?
Summary
Cattle ranching is responsible for approximately 80% of deforestation in the Brazilian Amazon, making it the single largest driver of forest loss in the world's most biodiverse rainforest. Brazil has the world's largest commercial cattle herd and is the world's largest beef exporter.

Key Points
- 1Cattle ranching accounts for approximately 80% of current deforestation in the Brazilian Amazon (Nepstad et al., 2008, Philosophical Transactions of the Royal Society B).
- 2The study found that the Brazilian cattle sector is responsible for one-fifth of all emissions from commodity-driven deforestation across the entire tropics.
- 3Crucially, the domestic market — which consumes 81-82% of Brazil's beef — was linked to 86-87% of the total deforestation risk.
- 4The study also revealed striking concentration in the supply chain: just three companies — JBS, Minerva, and Marfrig — handled approximately 72% of all Brazilian beef exports, with JBS alone accounting for over 40% of exports from the Amazon.
Evidence Summary
The connection between beef production and Amazon deforestation is one of the most extensively documented environmental relationships. Brazil is home to approximately 193 million head of cattle and is the world's largest beef exporter, supplying about one-quarter of the global market.
A groundbreaking study by Zu Ermgassen et al. (2020), published in PNAS (DOI: 10.1073/pnas.2003270117), traced Brazilian beef from over 2,800 municipalities through exporting slaughterhouses to 152 importing countries — a trade worth more than $5.4 billion per year.
Efforts to address the problem have had mixed results. The Amazon Soy Moratorium, signed in 2006, successfully reduced soy-driven deforestation by an estimated 18,000 km² over its first decade (Heilmayr et al., 2020, Nature Food). However, cattle-specific zero-deforestation commitments have been less effective. A study by Levy et al. (2023) in Global Environmental Change found that the G4 Agreement — signed in 2009 between Brazil's four largest beef exporters and Greenpeace — reduced cattle-driven deforestation by approximately 15% (7,000 km²) between 2010-2018, but full adoption by all firms could have prevented an additional 24,000 km² of forest loss.
